An object of the invention is to provide a fuel injection technique suitable for a spark-ignition internal combustion engine equipped with a first fuel injection valve for injecting fuel into a cylinder, a second fuel injection valve for injecting fuel into an intake passage, and a particulate filter provided in an exhaust passage thereof. The reflector may be combined with an existing element of the camera assembly, such as a leaf spring, or may comprise a separate, distinct reflector component. The motion converter, operating simultaneously in an opposing phase mode and in-phase modes, produces a complex motion of the workpiece. The maintenance dose is delivered via a pulse generator through a pair of helical electrodes via an electrically coupled nerve stimulation therapy lead independent of cardiac cycle. The section is disposed above the conductive patch and connected to a conductor plane at the top conductor layer.
